A method of constructing comprehensive reliability testing profile based on hardware and software

Test data generation relies on the profile during the reliability testing. However, software and hardware reliability test profile are considered separately in imbedded system, and it is not a true indication of the usage to the system. In this paper, we shall first contrast of the test profile construction flow of hardware and software, and find out the integrating of them. And then advance the method of construct comprehensive reliability testing profile based on hardware/software combination, which on the basis of improved software reliability test profile. Finally, by the factual for an Aeroengine Digital Control System, the rationality, effectiveness and feasibility of this method is proved. Furthermore, it supports the research of the embedded system reliability validation and evaluation.
